"Something really does shift in a wonderful way, and it refocuses things and in a weird way," he told host Robin Roberts. "It was a long time coming, but also put us in exactly sort of the right space. It's a wonderful thing."

The duo stunningly tied the knot in early August at their Bel Air, California estate — where the 75 guests on hand were told they'd be celebrating Theroux's 44th birthday.

Instead, they stood witness to the couple's unforgettable wedding, which even saw late night talk show host Jimmy Kimmel play the role of officiator.

"It was the biggest blessing in the world," Theroux said of Kimmel's performance. "It was the perfect tone for the night."

Both Theroux and Aniston have made public appearances separately since, but they appeared especially happy to share the spotlight together on Saturday.
